cutting and flaring fuel lines?

Anyone here Ever cut back their fuel lines and reflare them to accept direct AN fittings? I would like to have my fuel lines cut and fixed back by the firewall so I can run my braided line up to my manifold back by the firewall instead. After I cut the line, What fitting would I need to slide on first before flaring the fuel line?

It can be done.

However AN flaring tools are pretty expensive for the nice oens to do them properly(unless someone has a dectn cheaper one I'm not aware of)

What I would do, is find someone that has AN fittings/lines near you and scout out what kind of adapters they have and work backwards from there.

Like a metric/standard double flare w/ o-ring for fuel lines or the like and then decide on what fitting(s) to use on the fuel lines.

Also any place that does hydraulic type lines for industrial type stuff will more than likley have or be able to make what u need.

later

Thanks Jeremy, Where I work, their is a nice performance corner with lots of earls fittings. I could probably find what I need, I am just not sure even if such things existed in AN sizes to fit a standard size metal tube.

Travis, if you can get the lines off, take it down to American Street Rod on south sunrise next to smeding auto. I cannot imagine it being too expensive.

Those lines are like a milion feet long from front bumper to rear tank.

A good flaring tool runs +/- 150 bones. Might be worth the investment, Mr. Lazy.

You saying I just bolt those to the stock fittings on my fuel lines?

what angle does the stock fuel lines flare at?

I could cut the lines, stick on the stock fittings, reflare the new fuel line to the stock degree, reuse the stock fittings at the back by the firewall, and use these adapters.. hmmm

Stock fuel lines on a TPI are not flared. Its an o-ring fitting, the o-ring makes the seal whereas on a flare fitting the flare makes the seal.
I've used the Earls adapters, very simple. Just tighten up the nut on the factory hard line to the fitting and you have an AN connection ready to go. No hacking required.

I have the summit 37 degree flaring tool and it works great. I have tried it on aluminum and steel tubing with no problems. I believe the more expensive flare tools are only necessary for stainless line which is a real b!tch to flare.

Thats how I had it before, But I dont like the lines coming that far forward in the engine bay, but if its going to be a hassle, then I will go the adapter route again.

Wow, I just posted in another thread so I'll copy here...

I cut my hard lines underneath the car to remove everything from my framerails. I bought the 37 degree falre tool from Summit and it worked flawlessly for my project.

Tube nuts and sleeves work to attach the hose ends to the hard lines. Get one -6an tube nut and sleeve (feed line), one -5an tube nut and sleeve (return line), one -6an connector (two male ends for feed line to new hose), one -5an to -6an adapter (two male ends return line to new hose), four -6an hose ends, and some -6an braided hose. Then connect your new lines and feel great about your project.

BTW use straight hose ends for the hose meeting the old lines and I used 130 degree swivel fittings for the fuel rails.
